Description
Technical Field
The utility model relates to a supporting platform truck track sleeper technical field behind shield tunnel construction storage battery car, the shield constructs the machine specifically is a novel sleeper is used to the shield structure.
Background
In the past decades, the technology for developing underground space by tunneling in China has been established, but is continuously perfected. In general, the shield method has wide application range and prospect. At the present stage, large and medium-sized cities build subways or underground pipelines and use a shield technology.
The laying of the shield sleeper is particularly important on the premise that the requirement for the construction period is short and the safety performance is guaranteed to be large. The sleeper in the past passes through the bolt fastening on the section of jurisdiction, because at the section of jurisdiction in-process of assembling, the sleeper produces the rotation easily and leads to storage battery car and platform truck collision to make the platform truck derail, and fixing bolt's construction volume is also great moreover.
SUMMERY OF THE UTILITY MODEL
The above-mentioned defect to prior art, the utility model provides a pair of shield constructs uses novel sleeper has guaranteed the safe distance between platform truck and the storage battery car, effectively solves the section of jurisdiction and assembles the problem that the in-process probably leads to storage battery car and platform truck collision messenger platform truck derail, has not only improved the efficiency of construction, has still effectively ensured construction safety.
In order to achieve the above object, the utility model provides a following technical scheme:
a novel sleeper for a shield is formed by welding a trolley supporting platform and a fixed connecting section, wherein the trolley supporting platform is formed by a supporting surface and a side surface perpendicular to the supporting surface, and the supporting surface and the side surface are formed by vertically welding two steel plates with the same thickness; the bottom of the supporting surface of the trolley supporting platform is welded with a triangular reinforcing rib, and two sections of reinforcing steel bars are vertically welded on the central axis of the surface of the supporting surface; the fixed connection section is 12 type I-shaped steel, and the fixed connection section is welded with the side face of the trolley supporting platform.
The thickness of the supporting surface of the trolley supporting platform and the thickness of the steel plate on the side surface are 1 cm.
The height of each two sections of steel bars on the supporting surface of the trolley supporting platform is 6.5cm, the distance between each two sections of steel bars is 12cm, and the distance between each two sections of steel bars and each end of the trolley supporting platform is 5.3 cm.
And the welding included angle between the fixed connecting section and the side surface of the trolley supporting platform is 95-100 degrees.
The utility model has the advantages that: the novel sleeper for the shield has simple structure, convenient installation and stable operation, and improves the safety and stability; the safety distance between the trolley and the battery car is ensured, and the problem that the battery car and the trolley collide to cause the trolley to derail in the duct piece assembling process is effectively solved; the novel sleeper is laid without a pressing plate and without screwing bolts, and is convenient to install and dismantle, so that the construction efficiency is improved, and the construction safety is effectively guaranteed.
For a better understanding of the features and technical content of the present invention, reference should be made to the following detailed description of the present invention and accompanying drawings, which are provided for the purpose of illustration and description and are not intended to limit the present invention.
Drawings
The technical solution and other advantages of the present invention will become apparent from the following detailed description of the embodiments of the present invention with reference to the accompanying drawings.
Fig. 1 is the structural schematic diagram of the novel sleeper for the shield of the utility model.
Detailed Description
To further illustrate the technical means and effects of the present invention, the following detailed description is given with reference to the preferred embodiments of the present invention and the accompanying drawings.
Referring to fig. 1, a novel sleeper for a shield is formed by welding a trolley supporting platform and a fixed connecting section 5, wherein the trolley supporting platform is formed by a supporting surface 1 and a side surface 2 perpendicular to the supporting surface, and the supporting surface 1 and the side surface 2 are formed by vertically welding two steel plates with the same thickness; the bottom of a supporting surface 1 of the trolley supporting platform is welded with a triangular reinforcing rib 3, and two sections of reinforcing steel bars 4 are vertically welded on a central axis of the surface of the supporting surface; the fixed connection section 5 is 12 type I-shaped steel, and the fixed connection section 5 is welded with the side face 2 of the trolley supporting platform.
Further, the thickness of the steel plate of the supporting surface 1 and the side surface 2 of the trolley supporting platform is 1 cm.
Further, the height of each two sections of steel bars 4 on the supporting surface 1 of the trolley supporting platform is 6.5cm, the distance between each two sections of steel bars 4 is 12cm, and the distance between each two sections of steel bars 4 and the two ends of the trolley supporting platform is 5.3 cm.
Furthermore, the welding included angle between the fixed connecting section 5 and the side face 2 of the trolley supporting platform is 95-100 degrees.
The using method comprises the following steps: the welded novel sleeper is installed on a designated position, and the fixed connecting section is clamped on the segment hoisting protrusion to lean against the sleeper of the battery car, so that the novel sleeper is formed into a whole. The steel rail is laid between two steel bars of the supporting surface of the trolley supporting platform. In order to ensure the flatness of the steel rail after the novel sleeper is installed, a wedge can be inserted to ensure the straightness and smoothness of the steel rail.
Novel sleeper cyclic utilization: in the process of continuing the shield tunneling, the trolley continues to advance along with the continuous increase of the shield distance, the sleeper at the rear can be detached and placed at the front part of the trolley according to the mounting method, and therefore the sleeper can be recycled.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
